chompinthebit 269 #1 Posted August 12, 2020 The PTO-66 was introduced in 1966 to cater to the small farm. You could run 540rpm equipment like elevators on the farm with your garden tractor to keep your big tractors out working in the fields. This style is mid mount and is chain driven. 1 2 1 Share this post Link to post Share on other sites
